My invention is concerned with lubricators designed primarily for use with englnes, and

more especially with locomotive engines, and

is designed to produce a sight-feedlubricator that can be quickly filled when necessary from a supply'reservoir without substantially distracting the engineer from his work of watching the roadbed ahead of'him.

My invention'is further concerned with certain novel constructions insaid devices. all as will be fully described in the specification and particularly pointed ,out in the claims. f I I I To illustrate my invention, I annex hereto two sheets of drawings in which the same reference characters are used todesignate identical parts in all the figures, of which, 1 is a side elevationof a portion of'a locomotive having a lubricator' embodying invention applied thereto;

Fig. 2 is a side elevation of the supply reservoir and the associated hand pump which I preferably employ;

Fig. 3 is a central. vertical longitudinal section throughfthe supply reservoir and the associated pump; v

. Fig. 4 is a top plan view in section on the 7 line of Fig. 3; v

Fig. 5 is a detail in section on the line 5 5 of Fig. 3. Fig. 6 is a top plan viewof a portion of the apparatus illustrating a modified construction; r

Fig. 7 is a section on the line 7 of Fig. 6;and Fig. 8 is an elevation of'a fulcrum ring.

Referring first to Fig; 1, 10 is the boiler of a locomotive engine having the engineers cab 11 thereon arrangedin the customary manhas the condenser dome 1-3 on the top thereof,

which is connected by the pipe lt-with the interior of the boiler 10 above the water line.

On the bracket 15, secured to the side of the boiler, I fasten the'pump '16, which supports the supply reservoir 17 from which itdraws oil to fill the sight-feedreservoirJ12, being The condenser dome 13 is of any desired construction, and is secured to the reservoir 12 to co-operate therewith in thegcustomary 5 manner. v V p V e The auxiliary"reservoir 17 preferably consists of'a' nietalliecup ,of considerable'fsize," l

the top of which'is preferablyclosed by the 'cap' 48 preferably screwed thereon and pro vi ded with the knob e9 preferablyhaving the air passage5O therethrough. To strain the oil'and prevent anyjdirt possibly passing to the engineyl locate inythe bottom of the cup the ring 51, ofa diameter to fit the interlorof the cup and having thefine-mesh 1netalliciscreen52 secured in the top "thereof-ix j Conveniently toremove the 'scree nl secure in the center thereof the rod "53 terminating in the handle 54. 1 The bottom of'the cup is pro; l I

A passage 88 is drilled from itlie shoulder 70 to a point abevezthe inlet'port 64: so that'ras cl1ai' g'ecl,. he, diameter is. closed and theroil the piston head 66 is reciprocated backiand forth, the oil caught'by the rear of the piston can escape back to the inlet fi l. v The pipe 17 terminates in the angle cote 90 which pa int? the, ce ne tieefii t 'r 'rr l In order to sho'ivthe advantage of my im preved construction, Ifirst d escribe the process' such a .sightefeed reseivoir.

In the censtruction' so far described, it is necessary to mount the handle 74 so as to swing in a vertical plane.

. n se e c s:

however, it is,,desirahleatonmke it swing in se ne other plane than a vertical plane,

such" as a horizontal plane or any other angle, and for, this purpose I employ. the modification shown in Figs. 6,7 and 8, Where, instead of the lug 7Q, Iemploythe fulcrum r ng 791, \vlnclrh'as the ear 92 on, whicl rthe link "('7 r is pivoted. free ng Ellis clainped at any desired angle between the .i 'a'sher 93abutting aga nstashoulder 9% the barrel 15 and thenut95, which is screwe'do'n the elongated threaded end of the pump barrel inside of the packing nf'ut62. lVhile lha vjes oivn the packing (58 as unnecessarily elongated, itfwill be understood that it couldbe shortened by noving the shoulder farther out toward the end of the threaded portion. With this construction, it will be obvious that the handle 74 can be set at any desired angle which convenience of location and operationfinay require.

While I have shlovvn 4 and t l eq ib l J b? invention as embodied in the form which I at present consider best'afdaptefd t t out itspnrposes it will be pnderstood that it is capable of, nodific ations, ancl I do not desirelto be limited in theinterpretation of the following claiins exceptlas nay necessitated, by the stateof the prior ai't.
